Yammer API with AAD tokens Postman Collection
Published Oct 14 2019 12:35 PM 46.6K Views

We’re excited to inform that all Yammer v1 APIs now support the usage of Azure Active Directory (AAD) tokens. This is a critical step in Yammer’s authentication journey across web, mobile and platform to fully use AAD tokens instead of the Yammer OAuth token.


In this blog, we’d like to share steps for creating an AAD app, and visualizing Yammer API responses via the Postman client with AAD tokens.


Download the Postman Collection here.


1. Register a new app in Azure Active Directory

Go to https://portal.azure.com and register a new application.

13. Set variables in Postman

So you don't have to repeat typing, set a variable with the Yammer API URI prefix. Set yamURI to https://www.yammer.com/api/v1/

14. Select update and you are ready

Postman is now ready to make requests to Yammer API endpoints using Azure Active Directory tokens.


As Yammer integrates further into Microsoft 365, we’re excited for additional platform opportunities through the Azure Active Directory - this is just the beginning. We’re interested in all your feedback so be sure to comment on this blog or join us on the first Wednesday of every month in the Monthly Yammer Platform and API Office Hours.
